Can you be more specific in what it did not do?

Have you read [MS-KILE]: Kerberos Protocol Extensions:

It isn't so much what it did not do, but what it was able to do; it worked.

RFC 4757 specifies a message type (key usage) number of 8 should be used
for a TGS-REP response with an authenticator subkey. However, SAMBA and
Windows use 9. I would like to understand why.

Yes, and [MS-PAC].
